What happened to the children who lived through the Pandemic? Stan, Kyle, Cartman and Kenny survived but will never be the same Post Covid.

Red, a safe cracker who has just been released from prison, is trying to hold his family together as his past catches up with him in the form of Luc, a psychopathic contract killer who's seeking revenge for the death of his brother.

If Stan, Kyle and Cartman could just work together, they could go back in time to make sure Covid never happened and save Kenny's life. Traveling back to the past seems to be the easy answer until they meet Victor Chaos.
